As the title states, Will any mods be interchangeable between MKV GTI's and MKVI GTI's And GTI-R's ( thats if they follow the supposed engine configurements of the 211hp audi and the 230hp k04'd s3 engine respectively...)

Mainly interested in Intake, simple answer would be does a MKV GTI intake fit a 2.0t s3? and a3....?

Well, judging by the looks of the engine bay, it looks like the stock intake has a bit of a different design than the orginal intake on the MKV. My guess is that when it comes to intakes you may have to just settle on getting an updated one when the MKVI comes out.

However, the engine cover does seem to be alot smaller allowing for more 'creativity' when it comes to rerouting your induction setup.
